DRIVING MECEANISM FOR SLICING Application led July 22,

To all whom t may concern.'

Be it known that l, RUDOLPH BACHMAN, a citizen of the United States, residing at Laporte, in the county of Laporte, and State of Indiana, have inventedcertain new and useful lmprovements in Driving Mechanism for Slicing Machines, of which the following is a specication.

This invention relates to a power drive for slicing machines and has 'for its object the provision of mechanism ofV the class named which shall be of improved construe'- tion and operation.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawing and described in the following specification, and it is more particularly pointed out in the appended claims.

ln the drawinglig. 1 is a top plan view of a portion of a slicing machine having one embodiment of the present invention applied thereto; and

Fig. 2 is an elevation of the device shown in Fi 1, with parts in section.

lin atent No. 1,310,197, anted July 15, 1919, mechanism is shown y which a slicf ing machine is operated from an electric motor and the present invention is in the nature of an improvement on the mechanism of that patent.

Referring more particularly to the drawin the numeral designates a portion of a s icing machine frame having a drive shaft 11 mounted in a bearing 12. Integral with the bearing 12 is a socket 13 in which a stud shaft 14 is mounted. A sleeve 15 is journaled on the shaft 14 and provided with a pinion 16 which meshes with a spur gear 17 secured to the drive shaft 11. The gears 16 and 17 are enclosed in a housing 18 which is fastened to the frame 10 by screws 19. A

ulley 2O is journaled on the sleeve 15 in ront of the housing 18 and is provided with ball bearings 21 and collars 22 and 23 for holding it in place. A friction clutch member 24 cooperates with the inner face of the pulley 20, the clutch member 24 being splined on the sleeve and resiliently pressed into operative engagement with the pulley by. springs 25. The springs 25 bear against a flange 26 secured to the end of the sleeve 15 and a washer plate 27 is connected with the stud shaft 14 by a bolt 28 and holds 1922. Serial No. 578,681. i

the sleeve 15 in place on the stud shaft. The 'pulle 2O is operated by a belt 29 driven by a pu ley 30 secured to the shaft 31 of an electric motor 32. A tightener for the belt 29 comprises an idler 33 mounted on an arm 34 which is pivoted on a stud 35. The stud 35 is supported by a bracket 36 on the casing 14 and the arm 34 is provided with an angular rejection 37 having a spring 38 connected? therewith, the opposite end of the snring 38 being secured to a housing 39 for the outer end of the motor 32. rllhe housing 39 is connected with the frame l0 by screws 40.

The clutch 24is controlled by a lever 41 pivotally mounted at 42 on lugs 43 which are formed on the inner face of a bar 44. 'lhe bar 44 is supported by a pair of pins 45, the ends of which are threaded into the casing 18, as sho-wn at 46. The lever is provided with an extension 47 which engages a Wedge member 48 carried on an arm 49 formed integral with a sleeve 56, the sleeve being pivotally mounted on a pin 51 projecting forwardly from the casing 39. A bracket 52 engages the extension 47 to "prevent vertical displacement of the lever when operated by the wedge member 48. rlllhe sleeve is provided with a hand lever 53 having a grip 54 by which the lever may be oscillated to move the cam wedge 48. When the grip 54 is lifted the wedge 48 will be pressed downwardly to move the extension 47 inwardly and free the clutch 24 from the pulley 20. Movement of the hand lever in the op osito direction will release the eX- tension 4 from the cam 48 and permit the springs 25 to force the clutch 24 into operative engagement with the pulley 20. When the clutch and pulley are in operative connection and the motor 32 is running, the pulley will rotate the clutch member and consequently the sleeve 15, thus driving the main shaft 11 through gears 16 and 17.

In starting the machme the current will be turned on and when the motor has reached its full speed the friction clutch will be gradually brought into operation so that the machine may be brought up to speed without subjecting the motor to a sudden load. rlhe grip 54 is provided with a spring 55 which presses the grip inwardly to move apin 56 carried by the grip into engagement with openings 57 in a plate 58 for the purpose of holding the lever 53 inits dierent positions of adjustment. The

pin 56 may be disenga ed from the openings 57 by drawing outwar 1y on the grip 54.

Current is supplied to the motor 32 from a circuit59 controlled by a switch 60 which is mounted on a detachable cover or housing 61. The housing 61 is lsecured to the pins 45 and 51 by screws 62 and 63, respectively.

Lead wires 64 extend from the switch 60 to t e butt end contacts 66 and 68 will be separated from one another, and when the cover is replaced, electrical connection with .the

motor will be re-established automatically.
